WILBUR F, YOUNG, OF SPRINGFIELD, MASSACHUSETTS.

GAS-LIG HT H EATER.

SPECIFICATION forming part of Letters Patent No. 725,31 0, dated-April14,1903.

Application filed December 23, 1 902. Serial No. 136,354. (No model.)

To all whom it may concern: t

Be it known that I, 'WILBUR F. YOUNG, a citizen of the United States ofAmerica, and a resident of Springfield,in the-county of Hampden andState of Massachusetts, have invented certain new and usefulImprovements in Gas-Light Heaters, of which the following is a full,clear, and exactdescriptiou.

The object of thisimproved gas-light heater is to provide anapplia-nceof simple and cheap construction which may be employed inconjunction with an ordinary gas-burner and in the place of andsupported in the same man-- nor as the ordinary glass globe, whichwithout impairing the capabilities for illumination utilizes theproducts of combustion of the gas-light for heating the air in amaterial degree and yet the heating of the air being performed in amanner which does not vitiate the air by consuming the oxygen therein;and the invention consists in the appliance to constitute the combinedburner-globe and heater which is hereinafter described, and set forth inthe claims.

In the drawings, Figure 1 is a central vertical sectional view of thecombined globe and heater, shown as supported in its cooperativerelation to an ordinary gas-burner, Fig. 2 is substantially a plan viewof the same, portions being broken out in horizontal section.

Similar characters of reference indicate the corresponding parts in bothof the views."

In the drawings, A'represents an ordinary gas-burner tip which issurrounded by the therewith-connected usual circular skeleton frame I)for supporting the globe. In the present instance the globeA is composedof thin sheet metal comprising an inner wall (1, of inverted-dome shape,having circular bottom openings 6 and having circular central topopening f of less diameter than the bottom opening such globe,furthermore, comprising the outer annular wall g, which is ofconsiderably larger diameter thantheinner wall, the upper and lowerportions of which are inwardly merged to and have connection by anysuitable seam or joint with the inner wall d and all whereby thejacketed space or annular chamber 7' is produced,the same being entirelyinclosed, except in so far as there are the series of lower air-inletopenin gst' at the bottom and another series of airoutlet openingsk atthe top. The whole appliance, as described, made of thin light sheetmetahmaybe spun or struck up practicably gas-lightiiame, and the heatedair emerging at thetop of the device somewhat above the flame will befurther heated by the heat from the burner-flame, whichlatter, however,is

-far enough removed from the upwardly-issw ing heated air from thechamberj to be nonconsuming of the oxygen The inners'urface of the innerdome-shaped Wall will serve as areiiector for downwardly directingthelight,

such inner surface being, as desired, of polishedmetal, or it may bepainted white, 7

black, or any neutral or other color.

' v I am aware that various apparatuses have been proposed andconstructed for application in connection with a gas-light burner inwhich the air maybe heated by being brought ,within the range of thegas-light flame, and

it is not, of course, my intention to claim anything which would extendto cover any of these appliances; but,

Having thus described my invention, what I claim, and desire to secureby Letters Patent, isi v i 1. A combined gas-light globe, and airheaterconsisting of a metallic casing having an inner wallof dome shape withlarge central bottom opening and smaller top central opening, and havingan outer surrounding annular wall, the upper and lower portions of whichare inwardly extended and merged into, and joined to, saidinner wall,creating the inclosed annular air-heating chamber j, and said casinghaving a series of openings through its bottom outside of saidbottomcentral opening, and openings 70 through its 'top outside of said topcentral opening, substantially as and for the purpose set forth.

ICO

2. The combination with a gas-light burner j and. the circularsurrounding skeleton globesupporting frame, of a metallic casingremovably resting on said skeleton frame, which metallic casing, has aninner wall of dome i shape with large central bottom opening and smallertop opening, and having an outer separated and surrounding annular Wall,the upper and lower portions of which are merged into, and joined to,said inner Wall, creating the inclosed annular or heating chamber j, andhaving a series of openings '2; through its bottom outside of saidbottom central opening, and top openings 70, through its top out- 10side of said top central opening, substantially as described.

Signed by me at Springfield, Massachusetts, in presence of twosubscribing witnesses.
